Stick desiccators stop humidity/condensation in tight spaces
27 March 2009
Simply screwed into equipment or instruments to provide effective protection against humidity and condensation, Brownell stick desiccators are now available in a wide variety of sizes filled with a choice of silica gel or molecular sieve desiccant.
An ideal problem-solver wherever restricted space or access makes the use of standard desiccator assemblies or bags difficult or impossible, these units use a standard M5 threaded mounting hole. They are supplied with a sealing washer, require only a screwdriver for fixing in place and suit retro-fit or OEM applications.
Such items as optical sighting devices and camera lenses often require protection against humidity and condensation, but their size and design prevent the use of conventional desiccators which even may protrude into the optical path.
Silica gel desiccant has high drying efficiency and water vapour capacity in environments of moderate to high humidity and temperatures under 40ºC, with the advantage of being reactivated by heating when saturated. The molecular sieve option is particularly effective at creating very dry environments with low dew points and in higher temperature ranges up to 100ºC.
